PERFORATOR FOR PRINTING-PRESSES.

SPECIFIOAEIGN forming part of Letters Patent No. 688,097, dated December 3, 1901. Appiicflnon nea November 30,1900. serial No. 38,177. (No man.)

To c/,ZZ whom it may concern:

Be it known that we, GEORGE KENNEDY and ROBERT KENNEDY, subjects of the Queen of Great Britain and residents of New W estmin- 5 ster, in the Province of British Columbia and Dominion of Canada, haveinvented anew and Improved Perforator for Printing-Presses, of which the following is a full, clear, and eXact description.

The invention relates to printing-presses such as shown and described in the Letters Patent of the United States, No. 380,578, granted to us on April 3, 1888.

The object of the present invention is to provide a new and improved perforator which is simple and durable in construction, very effective in operation, and arranged to permit parallel as well as lengthwise and crosswise perforatingsimultaneously with printing and 2o to make connection with a line of perforations running at a right angle.

Theinvention consists of novel features and parts and combinations of the same, as will be fullydescribed hereinafter and then pointed out in the claims.

A practical'embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

tion of the same on the line 3 3 in Fig. 2.

Figs. 4 and 5 are transverse sections of the the same on the line 4: 4 in Fig. 3. Fig. 6 is a plan view of the device for actuating the driver. Fig. 7 is a sectional side elevation of Fig. 8 is a perspective view of the same. Fig. 9 is a perspective view of an alternative form of spring actuating device, and Fig. 10 is a perspective View of a modified form of the support for a plurality of spring actuating devices.

The perforator is mounted on a bar A, adapted to be locked up in a forni or chase B with the type, and the perforator is actuated by a 5o sprin g actuating device C, carried on a platen D (see Fig. l) of a printinglpress. The barA is formed with a longitudinally-extending recess A', in which fits a shaft F, carrying a perforating device G, in the form of serrated blades, punches, or the like, and the outer end of said shaft F is journaled in a thin plate A2, secured to the outer end ol the bar A, the inner end of said shaft also being provided with a journal F, Fig. 3, extending through an aperture in the thicker plate A3, secured to the inner end of the bar A, this journal carrying a crank and crank-pin F2.

On the crank-pin F2 is held an antifrictionroller F3, engaging a cam-groove H', formed in one side of a driver H, mounted to slide vertically in a quadrangular casing formed by a U-shaped plate A5, secured to one end of the bar A and normally held in an outermost position by a spring J, set in the bottom A4 of the casing integral with the bar A and projecting upward by means of a cylindrical opening into the center of the driver H,Which completely incloses the spring and rests upon the bottom of the casing when its downward vertical motion is finished. The guide-casing for the driver IVI is completed by the plate A3, secured to the inner end of the bar A.

The driver H when in an outermost position, with the perforating device inactive, is designedly made just a shade below the height of type B in the form, as shown in Fig. 3, and being thus slightly inked on its upper surface 4by the passage of the rollers;

leaves a sufficient impresston on the paper packing of the platen to indicate exactly where to set the actuating spring device on the platen, one impression of the form in which the perforator is locked up with the type being taken for this purpose before the actuating device is placed upon the platen.

The cam-groove I-l in one side of the driver H is so designed with a partly-straight and a partly-curved course as to admit of a subsequent downward movement of the driver after the perforatin g device has been brought into an active position, thus, with the actuating spring device, hereinafter more fully described, enabling the perforating device to be brought into the active or upright position well in advance of the impression and retain- IOO ing the said perforating device in that position until the paper' undergoing perforation and printing has become disengaged. The cam-groove also by its close-Working engagement With the crank-piu holds the driver from coming out of the casing in Which it describes its vertical reciprocating movement, and at the same time and by the same means accurately controls and holds the oscillating shaft, bearing the perforating device, at all points of its one-eighth of a revolution, and when at rest in the upright or active posi-- tion holding the oscillating shaft in this position firmly against the rest of the lugs F4 on the side AG of the bar A, hereinafter described.

The driver H is adapted to be pressed on by the actuating spring device C, previously mentioned, made of an arched rubber or metal and rubber spring or spiral form of metal spring with rubber tip and held in a carrier K, adjustable on a right-angle plate L, secured to the platen D, between one edge thereof and its clamp DQ as is plainly shown in Fig. 1. A clamping-screw N, carried by the plate L, engages an elongated slot K in the carrier K, so as to permit of adjusting the carrier and bringing the actuating device G in proper position relatively to the driver H, so that When an impression is made the actuating device C imparts a sliding motion to the driver H and moves the latter against the tension of its spring and imparts a rocking motion by its cam-groove H and crankpin F2 to the shaft F to bring the perforating device Ginto perforating position, as shown in dotted lines in Figs. 1 and 4, and perforate the paper at the time an impression is made thereon When the actuating device C moves out of engagement with the driver H, the spring J immediately returns the driver to its former position, so that a return rocking motion is given to the shaft F to swing the perforating device G out of an active position into an inactive position and out of the Way of the inking-rollers of the printing-press. (See Fig. 4.)

' In order to limit the turning motion of the shaft at the time the perforating device G moves into an active position, We provide lugs F4, which project from the shaft F at right angles to the perforating device and rest against one side A6 of the bar A, and in order to limit the return rocking movement of the shaft F at the time the perforating device G moves into an inactive position We provide a r t A7 on the face of the bar A opposite the sideiAG, and this rest A7 is inclined, as is plair'fily indicated in Fig. 4, and is so located that ithe perforating device G is out of the path of the inkiug-rollers, so that the latter are not injured and the perforating device is not inked. The perforating device G is extended at the outer end of the shaft beyond the said end, as is plainly indicated at G/ in Figs. 1 and 2so that this extension reaches l il to and connects with a row of perforations made at a right angle when it is found desirable to use two or more perforators in the form at the same time in this Way.

It will be obvious that two or more of our perforators may be used crosswise in the form at the same time parallel to one another. To provide for the Working of one or more perforators lengthwise in the form at a right angle to a crosswise perforation, as described, a modified form of support for a plurality of spring-actuating devices has been provided,

'which consists of an elongated plate L', (see Fig. 10,) formed at one end With a ixed foot and at the other end with an adjustable foot L2, secured in place on the plate L by aclamping-screw L3. The plate L extends across the platen D, the feet of said plate being secured in position on the platen by the clamp D. On the plate L are mounted to slide carriers K2, supporting actuating devices C, and the carriers K2 are dovetailed on the correspondingly-shaped plate L. The carriers K2 are adjustable on said plate L according to the position of the drivers H on the perforating devices, and said carriers K2 are held in place on the said plate L by small clampingscrews K3 to prevent the carriers from moving While in use on the printing-press.

NVe do not limit ourselves to the particular construction of the perforating device G arranged on the shaft F, as the same may be varied without deviating from our invention, it being understood that the said perforating device may be in the form of a serrated blade,

as previously mentioned, or in the form of aroW of dies, punches, or the like.
